Abstract (en)

[origin: EP0531617A1] Provided is a nonaqueous electrolyte secondary battery excellent in cycle life characteristic, stability in storage at high temperatures and low-temperature characteristic which is provided with an anode comprising a carbon material capable of doping and undoping lithium ion, a nonaqueous electrolyte and a cathode comprising a lithium-containing oxide, the solvent for the nonaqueous electrolyte being composed of the three components of an aliphatic carboxylate, a cyclic carbonate and a chain carbonate, the proportion of the aliphatic carboxylate being 10-70% by volume, that of the cyclic carbonate being 20-50% by volume and that of the chain carbonate being 10-70% by volume based on the total solvent. <IMAGE>
